Is it possible to browse for the file to link to? At the moment it appears the user has to already know the filepath and filename beforehand in order to use. this is a great limitation or am I missing something?

Hello!

We are currently working on a file browser add-on for the editor. It will be available soon!

Its been almost a month. Any progress?
And in the mean time, I can upload images, but what if I want to upload word docs, or pdfs... how do I do that.

Hello,
In the current version of the editor it is not possible to upload files.
You will be notified by mail as soon as the file browser addon is released.
